Improvement in axles for vehicles



UNITED STATES IMPROVEMENT IN AXLES FOR VEHICLES.

Specification forming part of Letters Patent No. 128,575, dated July 2, 1872.

' improved iron axle for wagons and other vehicles which shall be stronger without being heavier than iron axles made in the ordinary manner; and it consists in the axle constructed as hereinafter more fully described.

Arepresents one end of an iron axle having collar B and conical journals 0. In making this axle I take a bar which contains the usual amount of metal required for an ordinary iron axle, and,'by forging and upsetting, force the metal from center of bar and from each end to the collar-points B B, which are also swaged out of same bar. The purpose of this is to throw the weight and strength of condensed metal on the points of greatest strain in an and more desirable axle. In doing this it will 'be observed that I do not allow the bottom edge 0 of journal to be parallel to the horizontalbottom edged of body, because, if I did, the oil, after trickling. from the collar B to the end E, would not flow back along edge or Hence I oblique the bottom of journal on a line of declination from end to collar.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The within-described axle A, having the metal forced from center and ends toward the collars B, so that the body of the axle will be a gradual taper from the middle outward to the collars, and with the under side of the journal obliqued, as set forth.
